When sending out a pdf file of a drawing how do you "lock" it down so that it can't be edited? My company regularly inserts the PE stamp as a block with electronic signature and date on our plans prior to creating a pdf and emailing the file to another consultant or client.
Those settings are on the Security Tab of the Document Properties in your PDF Writer.
I use Adobe PDF, but I can set my security from the Properties (Custom Properties) of the Printer/Plotter, but it doesn't look like you can do that through the DWG to PDF plotter, so you will probably have to open the PDF in Acrobat afterward and change the settings...UNLESS someone knows of another way to do it.
In order to "'lock' it down so that it can't be edited?" you must create a password protected PDF. Unless I'm missing something, I believe that is the only way to "lock it down".
Unless it is different but I have a letter in pdf form that the only thing I can do with it is view and print it. When I open that particular file it doesn't ask for a password but it does have a digital signature...
Yes, a digital signature is different than just adding a password. In that case, you'll want to read this:
Perhaps you are talking about a post-processed item (example letter). If your office has a scanner and your CAD document is no larger tha the scanner will handle, then try printing the document to paper and then scanning to PDF.
Printing directly to PDF will save certain elements like your engineer's seals as separately inserted entities that can ba later manipulated somewhat like vector graphics.. Printing first, then scanning the print to PDF will eliminate a certain amount of editability of the document (much like the letter) changing everything to raster graphics.
You may also see if Adobe, ECopy, CutePDF, PDFwriter, AutoCAD PDF Print has any type of "flatten" option. Otherwise, password protect is gonna be your only other option.
To blow away your fantasy of a 'locked' PDF, zoom into a portion of the locked letter you note in this last reply, pretend it is your stamp. Start any screen capture routine (windows7 has a built-in Snipping Tool, other Windows versions have free 3rd party addons, and your keyboard as a printscreen button) and paste the result in a graphics program (say, Windows Paint).
Now you, and anyone one else, has your 'stamp' to do with as they wish in any software, including pasting it in AutoCAD.
As noted by others, explore Digital Signatures instead (no, they do not involve a traditional stamp and hand signature), but a paid service through a 3rd party.
